Description

A kind of current control electric switch

The utility model relates to the switch by the change operation in electric field or magnetic field, is specifically related to a kind of current control electric switch.

At present, electronic switch commonly used is particularly useful for the electronic switch on the electric heater, be by manually open, closure makes electric heater work, in use need repeatedly artificial the disconnection and energized, so promptly wasted electric power resource, and use inconvenient.

The purpose of this utility model just provides a kind of saving electric power resource, and a kind of current control electric switch easy to use.

To achieve these goals, the technical solution of the utility model is: a kind of current control electric switch comprises current control electric switch housing, its design feature is: be divided into two chambers up and down in the housing, top is air chamber, the bottom is a water cavity, be installed with spacer assembly between two chambers, by spacer assembly every seal isolation, lower chambers both water cavity is provided with water inlet and delivery port, between water inlet and the delivery port, the lower chambers upper end has hinge, and the hinged float trap that is positioned at bottom chamber that is equipped with is equipped with permanent magnet on the hinge on the float trap, and between float trap and spacer assembly, be installed with the compression spring, be provided with trigger switch in the upper chamber.

The utility model adopts said structure, current control electric switch housing is divided into two chambers up and down, top is air chamber, the bottom is a water cavity, be installed with spacer assembly between two chambers, by spacer assembly every seal isolation, lower chambers both water cavity is provided with water inlet and delivery port, between water inlet and the delivery port, lower chambers upper end has hinge, the hinged float trap that is positioned at bottom chamber that is equipped with on the hinge, permanent magnet is installed on the float trap, and between float trap and spacer assembly, is installed with the compression spring, be provided with trigger switch in the upper chamber.The compression spring makes float trap be in the water cavity bottom, and when water flowed, current forced float trap to move upward, and the permanent magnet on the float trap makes trigger switch send switching signal, finishes water flowing and then switches on, and the then outage of cutting off the water supply is easy to use, and has saved the energy.

Describe the utility model in detail below in conjunction with drawings and Examples;

Accompanying drawing shows the main cutaway view of the utility model embodiment;

The utility model comprises current control electric switch housing 1, be divided into by the isolation of spacer assembly 7 liquid sealings in the housing 1, following two chambers, top is air chamber, the bottom is a water cavity, lower chambers both water cavity is provided with water inlet 4 and delivery port 6, between water inlet 4 and the delivery port 6, the lower chambers upper end has hinge, the hinged float trap 2 that is positioned at bottom chamber that is equipped with on the hinge, permanent magnet 3 is installed on the float trap 2, and between float trap 2 and spacer assembly 7, be installed with compression spring 8, be provided with trigger switch 5 in the upper chamber, the upper chamber upper end is equipped with seal cover 9, the upper end that floats to water cavity on the permanent magnet 3 cooperates with trigger switch 5, trigger switch 5 is sent close and signal.When water is static or anhydrous in water cavity, owing to be installed with compression spring 8 between float trap 2 and the spacer assembly 7, compression spring 8 forces float trap 2 to get back to the water cavity lower end, and permanent magnet 3 is also got back to the water cavity lower end, and then trigger switch 5 sends cut-off signal, when water flows in the water cavity, water impact float trap 2 forces to move on to the water cavity upper end on the float trap 2, and permanent magnet 3 sends trigger switch 5 and closes and signal, make electric heating body work, flow heated water.

Certainly, water described in the utility model also can be other liquid.
